useAsync

useAsync is a custom hook that executes an asynchronous function and tracks its state.

const [flg, { toggle }] = useBoolean()
const { value, error, loading } = useAsync(
  async () =>
    new Promise<string>((resolve, reject) => {
      setTimeout(() => {
        if (Math.random() > 0.5) {
          resolve("Succeeded.")
        } else {
          reject(new Error("A pseudo random error occurred."))
        }
      }, 3000)
    }),
  [flg],
)

return (
  <VStack alignItems="flex-start">
    {loading ? (
      <Text>Loading...</Text>
    ) : error ? (
      <Text>Error: {error.message}</Text>
    ) : (
      <Text>Value: {value}</Text>
    )}

    <Button onClick={toggle}>Update state</Button>
  </VStack>
)

If you use this code, you need to add "use client" to the top of the file.

Usage

import { useAsync } from "@yamada-ui/react"

import { useAsync } from "@/components/ui"

import { useAsync } from "@workspaces/ui"
